TS Photoline 0.8x Focal Reducer and Corrector for Refractors from 102 mm Aperture

The corrector increases the speed of your refractor telescope and reduces the focal length for a larger field. The exposure time is reduced to 64%. In addition, the corrector corrects the field and creates pinpoint stars up to the edge of the image.
 

Adjust the corrector individually to your camera and refractor - no more adapter battle!

An essential part of the corrector is an integrated fine adjustment. By turning the knurled ring on the corrector, you can adjust the distance to the sensor extremely precisely. Once you have reached the desired distance, fix it with the clamping screw. In this way, you can determine the optimum distance via test exposures with the camera connected, without additional adapters and tuning rings. The camera does not rotate during fine adjustment.

The following settings from the innermost position of the adjustment to the sensor are recommended:

♦ aperture 102 mm / focal ratio f/7 - 69.87 mm
♦ aperture 107 mm / focal ratio f/6.5 - 69.0 mm
♦ aperture 130 mm / focal ratio f/7 - 66.17 mm
♦ aperture 140 mm / focal ratio f/6.5 - 65.8 mm
♦ aperture 150 mm / focal ratio f/8 - 63.34 mm
♦ aperture 155 mm / focal ratio f/8 - 62.57 mm
 

Connection to the telescope:

This Photoline Reducer has a M63x1 external thread on the telescope side. Many focusers already have this thread as standard. Adapters to other threads, such as M68x1, are of course available.
 

Application example - how to set the distance:

Setting the correct distance is very easy, as we will show in the following example:

♦ Telescope: refractor with 130 mm aperture f/7, thus 910 mm focal length.
♦ Camera: DSLR with 55 mm distance from the M48 thread to the sensor.

The working distance is 66.17 mm according to the table. From this dimension you simply deduct the 55 mm (distance thread to the sensor). This leaves 11.17 mm.

Simply turn the variable adjustment 11.17 mm outwards, this can be easily adjusted by the distance marking. You are now at the optimum distance and can start taking pictures.
